Host Susceptibility of CIMMYT’s International Spring Wheat Lines to Crown and Root Rot Caused by Fusarium culmorum and F. pseudograminearum

The destructive soilborne Fusarium species is one of the most serious challenges facing agriculture. Mycotoxins produced by spp. can induce both acute and chronic toxic effects on humans animals. Massive investments have been made in last few decades to develop an appropriate management strategy control cereals, particularly wheat, using genetic resistance other practices, with varied outcomes. purpose this research was find new sources culmorum F. pseudograminearum, which are wheat’s pathogens seedlings adult plants stages. In study, 26 lines were selected promoted from a total 200 spring wheat germplasm received CIMMYT Mexico plus 6 local check lines. 32 screened for their reactions under different environmental conditions. discriminant factorial analysis indicated that 7, 12, 5 resistant against field, greenhouse, growth room conditions, respectively. Four lines, L12, L19, L21, L26, found be jointly at seedling stages field greenhouse. On hand, only moderately pseudograminearum but not completely resistant, limited Interestingly, five (L10, L13, L17, L25, L28) shown properties species. To further evaluate yield performance best-selected trials conducted ± inoculum. highest values obtained three as well showed consistency its reaction greenhouse high (5342 kg/ha). Based result obtained, L26 potential improve culmorum-caused root crown rot; therefore, it should used crossing programs. Having Fusarium-resistant varieties will ultimately reduce rot symptoms increase grain quality reducing mycotoxin levels.
